And in the case of Outkast's grand Hangout Festival finale, that includes tens of thousands of cousins, aunts and uncles. Not to mention brothers, of which there were two who created what could go down as the greatest moment in Hangout history.

As the 2014 Hangout Music Festival came to an end, just about everyone left in the zip code were ankle-deep in sand watching as Big Boi and Andre 3000 hit the pinnacle of their 20-year reunion tour.

Throughout the historic set, all were reminded of exactly what made this duo one of the most legendary hip-hop groups of the 90s and 2000s. The Outkast show started with hits from "Stankonia," one of the top albums of 2000, as "Bombs over Baghdad" rained down on the Hangout Stage crowd, which swelled to epic proportions throughout the performance.

To call Outkast's set a "greatest hits" show is to do these hall-of-famers a great disservice. Yes, there were timeless pop favorites like "Ms. Jackson," "Players Ball" and "Elevators," but those were interspersed with two- and three-song groupings from the band's best albums, such as its debut, "Southernplayalisticadillacmuzik," "Speakerboxx/The Love Below" and "Aquemini."

And one of the strongest moments came from the title track to "Aquemini," when Big Boi and Andre 3000 flawlessly performed the two-part opus, which centers around how two men can become one unit when courageously pursuing their art. It was a beautiful reminder of how relationships forged through creation can be just as close as those born of blood.

The journey Outkast has been on throughout the past 20 years was center-stage as the pair talked with each other – and by default the waves of enrapt fans – about how long they've been doing what they love, together.

That path has rarely been smooth for the Georgia gents, but as one fan in the VIP area said as the fireworks spread the sky signaling the end of the festival, if you think Outkast is done, you weren't on the beach Sunday night.

When the music moved into one of their last albums, "Speakerboxx/The Love Below," the duo took turns on stage, performing their solo works that made up the double-record. But when they came together for the knockout track "Roses," the pair was back together for good until the curtain dropped.

Outkast, like other big-ticket arena acts, had full support on stage, which quashed even the most ardent detractors who might have screamed about possible lip-synching or recorded background music.

The brass section came alive for "SpottieOttieDopaliscious" off of "Aquemeni," and the soulful backup singers were amazing when Andre turned the slower track "Vibrate," from "Love Below" into the R&B dream "She Lives in My Lap."

But there weren't just paid players on stage Sunday night, which led to arguably the greatest moment in Hangout's five-year history. With a bevy of beauties behind him, Andre – who had donned his legendary silver wig and sunglasses – blew the beach out with the Grammy-winning "Hey Ya!"

If there was anyone who didn't know enough of that song to dance and sing along, they were probably on the other end of the festival helping Jack Johnson break down his stage.

When 'Kast played Coachella earlier this year, there were a few hiccups that left those who had lived through years of stagnation thinking the group couldn't rekindle the flame which swept the "Dirty South," and beyond, for years. But the Hangout Fest 2014 performance didn't just strike a spark, it burned the festival down, and will no doubt leave countless devotees – old, fresh, clean or dirty – begging for Andre 3000 and Big Boi to reunite again . . . this time in the studio.
